There are good reasons to suspect that a 60kWh Leaf is due out in 2019. So for current owners of a Leaf please, what things do YOU need to see to make you buy a new Leaf?
1) A secure way of knowing remaining battery capacity including history that is easy to access.
Secure, meaning can't be reset by a used car dealer or anyone else. A history makes events like a new battery install transparent to the potential buyer of a car. Must be accessible from the center console without special tools or software at minimum.
If I want to buy or sell an electric car, I need to know what the best estimate of the battery capacity is. Sure, I know that all measurements are not exact, so having either a stated accuracy (56 kWh plus or minus 2 kWh) or a minimum estimate (54 kWh, maybe more, but not less) is acceptable.
If I'm buying a car, I need to know what I'm buying. If I'm selling a car, I'll get a better price if the buyer can trust what I'm selling. A large fraction of the value of a EV is the battery pack condition. (23% of a new Bolt?)
2) Hilltop charge mode. Charge to 80% Or 85% Or even 90%. Or even better, give me multiple steps.
I want regeneration when I leave home. i live at the top of a hill.
On the rare days that I push range I'd like to charge to full. Make it easy to over-ride.
3) More leg room.
The center console intrudes into where my right leg would like to be. Please make it narrower.
4) A real battery temperature readout in degrees C and F. Sure, the TMS should be taking most of the temperature worries away. I'd like to know the actual battery temperature when driving up and down steep mountain roads, on long trips with multiple DCQC sessions, etc.
Ideally this should be a driver display, but I'd accept a center console screen with this and other "engineering details".
1) 19.2kW L2 charging. Or close to it. Most useful out in the wilds beyond DCQC. If I stop in a campground and get a 50 Amp plug, I'd like to use the 40 Amps that I can draw steady state from this plug. When I stop at an 80 Amp J1772, I'd like to draw 80 Amps.
2) Socialize the car. Provide a way to record trips similar to LEAFspy. And a way to display somewhat like http://www.leaflogger.com/
Perhaps just a bluetooth to cellphone link with an open API for third parties to write cellphone apps. Or perhaps using the car's cellphone link. Or even something else. Technology matters less than ease of use.
I like the ability to show someone my trips, where, when, battery charge level, outside temperature, battery temperature, ... Think of it as a social link to the car, making the car worth more to the owner, and more attractive to non-owners. Allow me to automatically fuzz out exactly where my home is, and other points where the trips start and/or end, for security and safety.
